Modifier and Type	Interface and Description
public interface	DecoderResultProvider Provides the accessor methods for the `DecoderResult` property of a decoded message.
public interface	Headers< the type of the header name. K, the type of the header value. V, the type to use for return values when the intention is to return `this` object. T extends Headers<K, V, T>> Common interface for `Headers` which represents a mapping of key to value.
public interface	ValueConverter<T> Converts to/from a generic object to the type.

Class Summary

Modifier and Type	Class and Description
public class	AsciiHeadersEncoder
public abstract class	ByteToMessageCodec<I> A Codec for on-the-fly encoding/decoding of bytes to messages and vise-versa.
public abstract class	ByteToMessageDecoder `ChannelInboundHandlerAdapter` which decodes bytes in a stream-like fashion from one `ByteBuf` to an other Message type.
public class	CharSequenceValueConverter Converts to/from native types, general `Object`, and `CharSequence`s.
public class	CodecException An `Exception` which is thrown by a codec.
pack-priv class	CodecOutputList Special `AbstractList` implementation which is used within our codec base classes.
public class	CorruptedFrameException An `DecoderException` which is thrown when the received frame data could not be decoded by an inbound handler.
public class	DatagramPacketDecoder A decoder that decodes the content of the received `DatagramPacket` using the specified `ByteBuf` decoder.
public class	DatagramPacketEncoder< the type of message to be encoded M> An encoder that encodes the content in `AddressedEnvelope` to `DatagramPacket` using the specified message encoder.
public class	DateFormatter A formatter for HTTP header dates, such as "Expires" and "Date" headers, or "expires" field in "Set-Cookie".
public class	DecoderException An `CodecException` which is thrown by a decoder.
public class	DecoderResult
public class	DefaultHeaders< the type of the header name. K, the type of the header value. V, the type to use for return values when the intention is to return `this` object. T extends Headers<K, V, T>> Default implementation of `Headers`;
public class	DefaultHeadersImpl< the type of the header name. K, the type of the header value. V> A concrete implementation of `DefaultHeaders` that allows for direct instantiation.
public class	DelimiterBasedFrameDecoder A decoder that splits the received `ByteBuf`s by one or more delimiters.
public class	Delimiters A set of commonly used delimiters for `DelimiterBasedFrameDecoder`.
public class	EmptyHeaders<K, V, T extends Headers<K, V, T>>
public class	EncoderException An `CodecException` which is thrown by an encoder.
public class	FixedLengthFrameDecoder A decoder that splits the received `ByteBuf`s by the fixed number of bytes.
public class	HeadersUtils Provides utility methods related to `Headers`.
public class	LengthFieldBasedFrameDecoder A decoder that splits the received `ByteBuf`s dynamically by the value of the length field in the message.
public class	LengthFieldPrepender An encoder that prepends the length of the message.
public class	LineBasedFrameDecoder A decoder that splits the received `ByteBuf`s on line endings.
public class	MessageAggregationException Raised by `MessageAggregator` when aggregation fails due to an unexpected message sequence.
public abstract class	MessageAggregator< the type that covers both start message and content message I, the type of the start message S, the type of the content message (must be a subtype of `ByteBufHolder`) C extends ByteBufHolder, the type of the aggregated message (must be a subtype of `S` and `ByteBufHolder`) O extends ByteBufHolder> An abstract `ChannelHandler` that aggregates a series of message objects into a single aggregated message.
public abstract class	MessageToByteEncoder<I> `ChannelOutboundHandlerAdapter` which encodes message in a stream-like fashion from one message to an `ByteBuf`.
public abstract class	MessageToMessageCodec<INBOUND_IN, OUTBOUND_IN> A Codec for on-the-fly encoding/decoding of message.
public abstract class	MessageToMessageDecoder<I> `ChannelInboundHandlerAdapter` which decodes from one message to an other message.
public abstract class	MessageToMessageEncoder<I> `ChannelOutboundHandlerAdapter` which encodes from one message to an other message For example here is an implementation which decodes an `Integer` to an `String`.
public class	PrematureChannelClosureException A `CodecException` which is thrown when a `Channel` is closed unexpectedly before the codec finishes handling the current message, such as missing response while waiting for a request.
public class	ProtocolDetectionResult< the type of the protocol T> Result of detecting a protocol.
public abstract class	ReplayingDecoder< the state type which is usually an `Enum`; use `Void` if state management is unused S> A specialized variation of `ByteToMessageDecoder` which enables implementation of a non-blocking decoder in the blocking I/O paradigm.
pack-priv class	ReplayingDecoderByteBuf Special `ByteBuf` implementation which is used by the `ReplayingDecoder`
public class	TooLongFrameException An `DecoderException` which is thrown when the length of the frame decoded is greater than the allowed maximum.
public class	UnsupportedMessageTypeException Thrown if an unsupported message is received by an codec.
public class	UnsupportedValueConverter<V> `UnsupportedOperationException` will be thrown from all `ValueConverter` methods.
